Consider the following factors regarding an industry : I. Capital investments II. Business turnover III. Labour force IV. Power consumption. Which of these determine the nature a size of the industry ?

Textbooks state that the size of an industry is determined by the amount of capital invested and the number of workers employed, along with the volume of production, which together define scale classifications such as household, small-scale and large-scale [1]. Separately, the availability and consumption of power (energy sources) is cited as a key determinant shaping the nature of industries (e.g., heavy versus light, location and production processes) alongside capital and labour considerations [2]. Combining these points, capital investment (I), labour force (III) and power consumption (IV) together determine an industry’s nature and size; hence option 1 is correct [2].
